Solve for x: −2(x + 3) = −2x − 6 NEED HELP PLZ:(
A: 0
B: 3 C:All real numbers
D:No solution
Answer:
The answer is C:All real solutions
Step-by-step explanation:
here are the steps in case u need them :)
Step 1: Simplify both sides of the equation.
−2(x+3)=−2x−6
(−2)(x)+(−2)(3)=−2x+−6(Distribute)
−2x+−6=−2x+−6
−2x−6=−2x−6
Step 2: Add 2x to both sides.
−2x−6+2x=−2x−6+2x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
Answer:
C: All real numbers.
Step-by-step explanation:
-2 ( x + 3 ) = -2x -6
-2 times x, -2 times 3
-2x -6 = -2x -6
Add 6
-2x -6 +6 = -2x -6 +6
-2x = -2x

-t^2 + 12t = 32
Answer:
t = 8, t = 4
Step-by-step explanation:
-t² + 12t = 32
-t² + 12t - 32 = 0 (Subtracted 32 on both sides.)
t² - 12t + 32 = 0 (Divided by -1 on both sides.)
(t - 8)(t - 4) = 0 (Factor.)
t - 8 = 0 t - 4 = 0
t = 8 t = 4

I forgot how to divide fractions properly. please send help.
Answer:
2.5 or 10/4
Step-by-step explanation:
2÷4/5
Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,
2/1÷4/5
But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)
2/1×5/4
And tadaa! you get your answer
10/4
You can also simplify it!
5/2
Solve for d in the proportion.
10/15 equals d/12
Answer:
8
Step-by-step explanation:
Since there are two fractions, it is easiest to cross multiply the fractions before doing anything else. Basically:
10/15 = d/12 becomes 120 = 15d.
then you just divide 15 to both sides to get your answer:
d = 120/15, which is the equivalent of d = 8.
Find the value of x
12x
6x+28
Your answer
Step-by-step explanation:
Hey there!
By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.
So,
2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)
8x + 28°=180°
8x = 180° - 28°
8x = 152°
[tex]x = \frac{152}{8} [/tex]
X = 19°
Therefore, X = 19°.
Hope it helps...
Answer:
x=19
Step-by-step explanation:
These are same-side interior angles. The Same-Side Interior Angles Theorem states that if two parallel lines are cut by a transversal, then the same side interior angles are supplementary. This means that the sum of the two angles is equal to 180°.
2x+6x+28=180°
8x=180-28
8x=152
x=19
Question 4 Multiple Choice Worth 1 points)
(04.02 LC)
What is the solution to the following system of equations?
X - 3y = 5
2x + y = 10
(5,0)
(0,5)
(7,0)
(0,7)
Answer:
( 5, 0 )Step-by-step explanation:
x - 3y = 5
2x + y = 10 multiply by 3 to eliminate y and solve for x
x - 3y = 5
6x + 3y = 30 then add
7x = 35
simplify:
x = 35 / 7
x = 5
substitute x = 5 back into the eq.2
2x + y = 10
2(5) + y = 10
y = 10 - 10
y = 0
therefore the answer is ( 5, 0 )
4) The triangle on the right is an equilateral
Find the value of X and Y
Answer:
angle Y is 29 degrees
angle X is 120 degrees
Step-by-step explanation:
Well, if the triangle is an equilateral, then all the angles are equal to
60 degrees
that means the the angle at the top point is 60+31 = 91 degrees
the right point is 60 degrees
every triangle has 180 degrees total
180 - (91+60) = 29 degrees
NOW FORGET ABOUT THE EQUILATERAL FOR A BIT
180 = 31+x+29
simplify
180 = 60+x
subtract 60 from both sides
120 = x

The answer is~ no solution
Step-by-step explanation:
its no solution because
3x−3(x+1)=3
Step 1: Simplify both sides of the equation.
3x−3(x+1)=3
3x+(−3)(x)+(−3)(1)=3(Distribute)
3x+−3x+−3=3
(3x+−3x)+(−3)=3(Combine Like Terms)

Answer:
y = x - 8
Step-by-step explanation:
In order to solve this, we need to use point-slope form.:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - (-8) = 1(x - 0)
y + 8 = x
y = x - 8

Finding the Slope of a Line from a Table
What is the slope of the linear function represented in
the table?
y
o
.
Answer:
m = rise / run = 1/7
Step-by-step explanation:
Recall that the slope of a line is m = rise / run.
Here we look at x first (to calculate the run): x begins at -7 and ends at 0. Thus, the run is 0 - (-7), or 7.
Now look at how y behaves (find the rise): y begins at 0 and ends at 1. Thus, the rise is 1.
Therefore the slope of the line connecting the two poings given is
m = rise / run = 1/7
Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. The total cost in
dollars for ordering 5 tickets is $108.00. Which linear function represents , the total cost, when x tickets are ordered?
c(x) = 5.50 + 20.50x
c(x) = 5.50x + 20.50
c(x) = 5.50 + 21.60x
c(x) = 5.50x + 21.60
Answer:
The correct linear function is c(x) = 5.50 + 20.50x.
Step-by-step explanation:
It's a linear function, so that means it uses y=mx+b. It says "per ticket" which means that the ticket cost is the slope, or m, of the equation. The service fee would be added on as a one-time fee, making it the y-intercept, or b. In order to find the cost of the tickets, you had to subtract the service fee from the total cost, then divide by how many tickets were purchased. You can set this up by plugging in what you know.
[tex]108=5.50+5x[/tex]
Subtract the 5.50 from both sides, leaving us with:
[tex]103.50=5x[/tex]
Now, this equation tells us how much 5 tickets cost, but we want how much it is per ticket. That means now we have to divide both sides by 5:
[tex]20.50=x[/tex]
Thus, one ticket is $20.50.
[tex]c(x)=5.50+20.50x[/tex]
The linear function is c(x) = 5.50x + 20.50
Let the cost of the tickets be represented by x
Therefore, 108 = 5.50 + 5x
Collect like terms
5x = 108 - 5.50
5x = 103.50
Divide both side by 5
5x/5 = 103.50/5
x = 20.50
Therefore, a ticket costs $20.50
In conclusion, the total cost, when x tickets are ordered will be c(x) = 5.50x + 20.50.
